System and method for providing a congestion optimized address resolution protocol for wireless ad-hoc networks
First Claim
1. A node, for use in a wireless ad-hoc communications network, and being adapted to transmit and receive data packets to and from other nodes in said wireless ad-hoc network and to operate as a router to route other data packets destined for said other nodes in said wireless ad-hoc network to said other nodes, said node comprising:
- an address resolution protocol module, adapted to generate an address resolution protocol (ARP) request for a media access control (MAC) address corresponding to an Internet protocol (IP) address, said MAC address being associated with a device; and
a transceiver, adapted to transmit said ARP request for delivery to an access point of a network portion without broadcasting said ARP request to a plurality of said other nodes in said wireless ad-hoc network, said access point being adapted to enable said node to communicate with said network portion.

Abstract
A system and method for providing a congestion optimized address resolution protocol (ARP) for a wireless ad-hoc network. The system and method enables a node in the wireless ad-hoc network to issue an ARP request without the need to broadcast the request to all of the nodes in the wireless ad-hoc network, to thus minimize radio traffic on the wireless ad-hoc network for handling the ARP request. The node includes an address resolution protocol module which is adapted to generate an ARP request for a media access control (MAC) address corresponding to an Internet protocol (IP) address, and a transceiver which is adapted to transmit the ARP request for delivery to an access point of a network portion, such as a core LAN of the network, without broadcasting the ARP request to a plurality of other nodes in the wireless ad-hoc network. The transceiver can transmit the ARP request to the access point directly or via other nodes in the wireless ad-hoc network.

11. A method for controlling a node in a wireless ad-hoc communications network to perform address resolution protocol (ARP), said node being adapted to transmit and receive data packets to and from other nodes in said wireless ad-hoc network and to operate as a router to route other data packets destined for said other nodes in said wireless ad-hoc network to said other nodes, said method comprising:
-
controlling said node to generate an address resolution protocol (ARP) request for a media access control (MAC) address corresponding to an Internet protocol (IP) address, said MAC address being associated with a device; and controlling said node to transmit said ARP request for delivery to an access point of a network portion without broadcasting said ARP request to a plurality of said other nodes in said wireless ad-hoc network, said access point being adapted to enable said node to communicate with said network portion. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)

21. A computer-readable medium of instructions for controlling a node in a wireless ad-hoc communications network to perform address resolution protocol (ARP), said node being adapted to transmit and receive data packets to and from other nodes in said wireless ad-hoc network and to operate as a router to route other data packets destined for said other nodes in said wireless ad-hoc network to said other nodes, said computer-readable medium of instructions comprising:
-
a first set of instructions, adapted to control said node to generate an address resolution protocol (ARP) request for a media access control (MAC) address corresponding to an Internet protocol (IP) address, said MAC address being associated with a device; and a second set of instructions, adapted to control said node to transmit said ARP request for delivery to an access point of a network portion without broadcasting said ARP request to a plurality of said other nodes in said wireless ad-hoc network, said access point being adapted to enable said node to communicate with said network portion. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30)
